Provided is a method of preparing a granular feed additive. When the method of preparing a granular feed additive according to one exemplary embodiment is used, it is possible to prepare a granular feed additive including a high content of basic amino acids while preventing hygroscopicity and agglomeration caused by the basic amino acids. In addition, since the method of preparing a granular feed additive according to one exemplary embodiment may omit a process of using hydrochloric acid, which is generally used to neutralize basic amino acids, it is possible to simplify the process and to solve process problems caused by the use of hydrochloric acid.

Method of preparing granular feed additive

The present disclosure relates to a preparation method of a methionine-metal chelate, and the methionine-metal chelate, which is prepared by first reacting Ca(OH)and methionine and adding metal chloride salts, can be used as feeds and feed additives.

Methionine-metal chelate and manufacturing method thereof

The present disclosure relates to a preparation method of a methionine-metal chelate, and the methionine-metal chelate, which is prepared by first reacting Ca(OH)and methionine and adding metal nitrate, can be widely used as feeds and feed additives.

The present application relates to a method for preparing L-methionine crystals with an improved bulk density. As the L-methionine crystals prepared according to the method for preparing L-methionine crystals of the present application may have a bulk density of up to 800 g/L, the L-methionine crystals are expected to reduce storage and transport costs of L-methionine powder and improve working conditions due to improved fluidity of the powder.

Disclosed herein is a cylindrical secondary battery constructed in a structure in which a crimping region, at which a cap assembly is mounted to the open upper end of a cylindrical container having an electrode assembly mounted therein, is formed at the upper end of the container, wherein the crimping region is constructed in a structure in which the upper end of the crimping region is gently bent at a predetermined radius of curvature (R), such that the crimping region surrounds a gasket located at the inside of the crimping region, the bent front end extends inward, such that the bent end presses the gasket, and an inclination of a predetermined angle is formed at the sidewall of the crimping region, such that the upper part of the crimping region is directed inward. According to the secondary battery of the present invention, the sealability of the gasket is improved, and external impacts are partially absorbed by the inclination formed at the crimping region. Consequently, the deformation of the crimping region is minimized, whereby the leakage of the electrolyte is prevented, and the safety of the battery is greatly improved.
